The z24 model came with a 2.4L DOHC engine and uses a Air/Oil separator(no maintenance required)and does not have a PCV. The 2.2L OHV engine comes in the base model Cavalier and its on the top center of the valve cover at the back of the motor. There is a 1/2' black rubber hose going from the pcv under the plenum. It just pulls out. no tools required to replace it.
